Accessibility testing is a combination of automated tests and manual evaluations in order to assess the accessibility of a website. For example, while an automated test can identify if there is an accessibility violation such as missing alternative text for an image, it cannot accurately assess the quality of the alternative text when it is included.
Automated testing tools help determine if a webpage meets certain accessibility guidelines. However, they only find about 25% of accessibility issues, the remainder needs to be manually assessed. Below are a few tools that can be used to run an automated test.
- Compliance Deputy Toolbar - Browser-based toolbar for testing individual pages against the CSU ATI Accessibility Checkpoints.
- WAVE Accessibility Tool - Online web accessibility evaluation tool for testing individual pages.
Many accessibility standards require human judgment and must be evaluated manually. Below are a few tools and checklists to assist you with manual testing.

- Fangs - A screen reader emulator for Firefox.
